- THANK YOU so much !

What I have read/heard for filling in the spaces left vacant by the elements is the mix 50/50 sawdust and fireclay; make a stiff clay (putty) out of it and fill it in.
Thanks for showing this. I am waiting until you fire this one up and see how it goes before I rip into my old electric Skutt and follow your example.
Keep up the good work Simon it looks great ! You've got me looking on Craigslist for a old electric kiln now !! Great idea !
Do not use that cement IN the kiln. It blisters and flakes. I used the exact same cement in my raku kiln. Failed at cone 06 and made a mess.
Preliminary research didn't give me much to go on. Weed burners being used for burning weeds and not usually put to multiple-hour usage, it's hard to gauge what the propane/hr use is.
I need to know what you want to do with your kiln to make a dollars estimate. I will say though that this is a bit of an envelope pushing way to fire pots, and you should just put this thought down if you want to move into it without monetary risk.
Thanks for the videos, Simon. How did you cut through the furnace bricks for your burner and flue ports? I wonder if creating a flue inside the kiln to channel the gasses from the top of the kiln to below that floor plate might keep more of the heat where you want it? You probably already tried it.
I don't have any experience building kilns, (yet) but it seams to me you will have the 'IN' draft being CROSSED by the 'OUT' draft on the way out, at the spaces between the bricks supporting the bottom kiln shelf.
So I guess I agree with danielsolowiej.
Won't the exiting gases divert at least some of the entering flame out the flue at the bottom of the kiln, before it circulates.
Just my two cents

Why don't you look up the cost of propane tanks at your local fuel supplier. Phone someone up and ask them the sizes for the tanks and how much to fill them up.
What I know about the burners from my own research is that you'll want a relatively large tank so that prolonged usage doesn't freeze the gas in the cylinder. Expanding the gas takes energy and if the tank goes to -40 the gas will become liquid and no longer flow out the top. I'll do a quick bit of research for the gas usage/hr now.
LOL@the roasting comment. Nothing I love more than a great sense of humor! Come and fire this puppy up so I can see how it goes. I want to get busy on mine when this is tested:)
Simon, Mark Ward from Ward burners told me for a kiln my size (Just like yours in Spain, from the self reliant potter) needs 6 feet of chimney. My kiln struggled to reach cone 10 until I Increased the chimney height. I'm interested to see if this will reach temp. I use the same exact burner for my raku kiln. One burner heats it to temp in 30 minutes. Check out my latest videos.
nice video
What's the reason for 2 burners instead of one? Because of the high temperature you want to reach?
well done ..
I cut a shelf like that with a diamond cutting wheel on my angle grinder, about $12 at Home Depot. Wear a dust mask.
